71: Color-changing ink? Yes, is it like the one the anchor showed?

He must have been blinded by greed at that time.

The moment he saw Su Yu, he didn't immediately choose to close his account and end the broadcast; instead, he naively believed that Kuaishou Official (Platform) would promote his live stream.

Perhaps this is karma.

He used the other party's traffic to build his account, and in the end, he returned all the traffic to the other party.

The remarks on the Kuaishou Platform that slandered Su Yu have now collapsed on their own!

After all, even he, the leader of the anti-fans, had completely fallen for the other party's exquisite painting skills, not to mention the fans he led to sing a different tune, and those who didn't know the truth.

Since then.

The leaderless anti-Su group completely dispersed.

On Su Yu's side.

Having streamed for four hours straight, meticulously replicating all the patterns on the dollar bill, he also needed a moment to rest.

This replication took almost half the time compared to the last one, and it was done during a live broadcast.

He needed to interact with the audience in the live stream while painting, which sounds easy but was not easy at all.

Fortunately, he succeeded on his first attempt.

This also completely relieved Tang Xiaoyuan, who had been on tenterhooks in the live stream.

Streamers like Su Yu feared nothing more than a live broadcast going wrong.

Although the live stream seemed very popular, he was also constantly watched by many anti-fans.

As long as he made any mistake during the live stream, even if he didn't ruin the painting, even if he just made a small error, he would definitely be seized upon by these people and severely criticized.

Now that he had safely passed the first hurdle, the subsequent steps would be much simpler.

"The Streamer is amazing, hand-painting a dollar bill! Is there anyone knowledgeable in the live stream who can explain what level this is!"

"What level? It's a level I can't reach, that's for sure!"

"Just looking at the imitation and handling of the lines and details, the line drawing skill should be considered top-notch in China. As for other aspects of his painting skills, the Streamer hasn't shown them in the live stream, so it's hard to judge."

"The dollar bill has been drawn, now all that's missing is the application of various anti-counterfeiting technologies. If those could be added too, that would be too much!"

"Forget it, forget it, everyone, don't make it difficult for the Streamer. He's been streaming for so many hours straight, who still has the energy to research that stuff."

"Exactly, the Streamer is challenging hand-painting a dollar bill today, not counterfeiting it! Besides, even if the Streamer dared to counterfeit it, would the Kuaishou Platform dare to broadcast it?"

"True, if the Streamer really managed to counterfeit the dollar bill, I'm afraid the entire USA would be unable to sit still."

Watching the audience's discussions in the live stream, Su Yu couldn't help but curve his lips into a faint smile.

As expected, the system rewards were indeed far-sighted.

Since it gave him specialized painting skills, it naturally also had to be paired with corresponding basic color-changing ink and watermark technology.

And these two technologies had actually been researched before he started streaming, but they were not publicly revealed in the videos he posted.

This was his finale performance reserved for today's live stream.

"Teacher Su Yu, today we are honored to witness the entire process of your hand-painted dollar bill with all the viewers in the live stream."

"I never expected Teacher Su Yu to not only have profound research in aerospace technology but also such accomplishments in painting!"

"He truly lives up to being the well-deserved youth model of our China."

While Tao Ji was filled with emotion, he also did not forget to lavish praise on the young man before him.

When the Kuaishou Platform was first established, its main purpose was to make it convenient for everyone to record their wonderful lives.

However, with the continuous development of live e-commerce in recent years, the invasion of various commercializations and scripts has led to more and more Streamers like Big Lazy appearing on the platform.

They claimed to be making profits for their fans, but in reality, they were exploiting them!

They turned the initially pure and simple video recording and live sharing into profit-making with commercial nature. And pure Streamers like Su Yu were becoming increasingly rare, now almost like a phoenix's feather or a qilin's horn.

Meeting him today, Tao Ji felt enlightened.

"Teacher Su Yu, since the dollar bill has been completely drawn, I now announce that our miracle challenge today..."

Tao Ji's words were cut short before he could finish, as Su Yu urgently interrupted him.

"Wait, I don't think this counts as a successful challenge yet!"

Su Yu looked up and slowly took out a pre-prepared palette of colored paints from the side.

Tao Ji was stunned.

Big Lazy was in despair.

The audience in the live stream also held their breath.

No, this doesn't count as a successful challenge?!

He live-streamed drawing a bill identical to the dollar under the gaze of the entire internet. If that doesn't count as a successful challenge, what does?

"Could it be that the Streamer really wants to add the anti-counterfeiting technology to the banknote as well?"

"No way. If I remember correctly, anti-counterfeiting technology should be another field, a form of technical encryption?"

"Streamer, don't mess around. Quickly let the Kuaishou Official (Platform) give certification first, otherwise, once you're offline, there will be people who know nothing questioning this and that in the comment section."

"Exactly, exactly, Streamer, I advise you to be kind! If you really add the anti-counterfeiting technology, I will, I will..."

"Oh my God, what am I seeing! This Streamer is too crazy, oh no, absolutely do not let him counterfeit our American currency!"

Su Yu ignored the doubts in the bullet comments and took out the pre-prepared palette.

Inside it was the color-changing ink he had prepared in advance.

With the system's reward, making such a thing was child's play for him.

Under everyone's watchful eyes, Su Yu took out a fine brush, then dipped it in some prepared ink and gently drew a line on the white paper.

A clear silver trace appeared on the white paper.

"Coloring? I knew why he didn't end the challenge; turns out the Streamer wants to color the drawn banknote."

"But where would the silver ink be applied? On the numbers? I remember only the numbers on the dollar bill are silver, right."

"No, the ink on the numbers isn't just plain silver; I remember it's like a rainbow of colors."

"Don't talk nonsense if you don't know, what do you mean a rainbow of colors. That's color-changing ink!"

"Many banknotes have used this anti-counterfeiting technology. The ink doesn't have a fixed color; under the refraction of light, by simply changing the viewing angle, it can display different colors."

"Look, is it... is it... is it what the Streamer... is what the Streamer is showing?"

The appearance of one bullet comment brought countless others to an abrupt halt.

Only to see Su Yu holding the paper with the silver trace, slowly bending it, and then unfolding it.

In front of the high-definition live camera, the originally silver ink marks, under the sunlight, suddenly reflected beautiful, colorful light!

The light was dazzling and mesmerizing.

It made people lose themselves in a trance.
